TRUCK FRAME.

T 0 all whom it may concern:

Be it known that I, RALPH E. WIIDER, a citizen of the United States, and a resident of Bethlehem. in the county of Northampton and State of Pennsylvania, have made a certain new and useful Invention in Truck Frames, of which the following is a specification.

My invention relates to trucks for railway cars and particularly to those for freight cars and to that portion known as the side frame and its appurtenances. M truck frame consists essentially of an lntegral metal plate. formed with the upright portions spaced apart; the top member being integral and the side members bent downwardly therefrom; the end members projecting longitudinally of the frame and provided with bearing surfaces adapted to rest on the tops of the journal boxes; the ends of the side portions extending downwardly and inwardly inclined from the tops of the journal box bearing portions; the bottom portion being substantially horizontal, the whole being provided with openings centrally arranged, of substantially rectangular form to receive the end of the bolster; the lower portion of the opening being provided with a spring seat, and the sides of the o en-I ing being provided with bolster guides. he two upright web portions, which are spaced apart, are secured together by means of a ing integral stiffening flanges aroun .40

bent plate, the flanges of which are riveted near the lower portions of the side members] and preferably also to the inclined portions of the side members. I also provide tyvo tri--.

angular openings with rounded, corners in grojectthem. The structural portion of my truck side .each side portion, having internally frame is thus practically composed of one sheet or plate of metal which is formed or. folded together at its upper portion, thev I v the compi'ession when driving and to further v downwardly projecting side members bein spaced apart and the lower portions secu together-by a bent plate secured to both.

Having thus given a general description of my invention, I will now, in orderto make the matter more clear, refer to the annexed she'et of drawings which'form part of this dated July 2, 191B,-Seria1 No. 230,829, filed April 25, 1918. Application for reissueflled August 18, 1923. Serial No. 658,170. l 7

specification and in which like characters refer to like parts. 7

. Figure 1 is a side elevation of a railway car truck provided with a side frame emsubstantially upright spac'ed apart and substantially parallel to eachother, 4 is the central opening of substantially rectangular outline with rounded corners, the edgesof the plate adjacent the opening being provided with integral outwardly extending flanges 5. The webs are further provided with triangular openings 6 with rounded corners, these being provided with inwardly extending flanges 7 formed integral with the web portions. The entire lower portions and inclined side portions of the frame are rocured together by means of the bent'lplate' 14. the flanges of which adjoin and are riv eted to the webs 3 as illustrated, by means of the rivets 15; The rivets 15 are'preferably through rivets and are provided with sleeves or thimbles 16 between the .flanges'to resist stiffen the structure when the rivets are 1 driven. The plate 1 1 is formed, as shown,

with flanges by doubling or folding the.

plate, and the intermediatejpart of the outwardly extending portions--22" rests upon the vupper surfaces of the flanges 5 and '80 vided with integral outwardly exten ing; I there are two side bent plate are 22, and journal boxes 23 of the usual type are used. Bearingplates 10 are secured to the laterally projecting ends 'of the truck frame to form seats to bear upon the tops of the journal boxes. Holes '11 are provided in the journal bearing plate 10, and other openings 12 are provided near the ends of the upper flange member 2 'through which the journal box bolts 9 may be passed for securing the journal boxes to the truck frame. The usual pedestal tie bar 13 is shown as riveted to-the truckframe and secured to the lower portions of the journal boxes by means of the journal box bolts.

From the foregoing, itrwill be apparent. that I provide a truck side frame, the main or body portion of which is constructed from an integral metal plate folded at the top, as indicated at 2,.to provide downwardlyextending and substantially parallel side webs 3 having converging and downwardlyextending side edges 24 which join intermediate bottom edges 25. The rectangular flanged openings 4 are arranged above the:

bottom edges 25 and the triangular openings 6 are arranged above the inclinedor converging edges 24. This construction provides for an upper arch or compression member 27, a lower arch or tension member 28, and connecting column members 29, the members being separated and defined by the openings 4* and 6. The upper member 27 projects over the journal boxes 23 and it is integral with the upper ends of the column members 29 and with the upper ends of the inclined side portions 30 of the lower member 28. The lower member 28 is integral with the lower ends of the columnmem'bers 29 and includes a horizontal or bottom portion 31 arranged between the inclined side portions 30. The upper member consists of the bent over or folded portion, indicated at 2, portions of the webs 3 including the top flanges of the openings 4 and 6, and the horizontal ends of the lower web flanges 8. The column members 29 comprise opposed portions of the web and flanges of adjacent sides of the triangular and rectangular openings 6 and 4. The lower member 28, comprised by-the inclined side portions 30 and by the bottom portions 31, includes opposed portions of the webs adjacentflanges of embraced withinthe scopeof my invention or as pointed out in the claims.
